[Solved]CSS & JavaScript via function

[anymvs]

Hello guys am working with google <script async> the whole situatios

so, google below refers to the following::

:source:

<script>
var node = document.createElement('script');
node.type = 'text/javascript';
node.async = true;
node.src = 'example.js';
// Now insert the node into the DOM, perhaps using insertBefore()
</script>

So I have convert the above java according to google as,

<script type="text/javascript">
var fcb_js = document.createElement('script');
fcb_js.type = 'text/javascript';
fcb_js.async = true;
fcb_js.src = '/clientscript/vbulletin_facebook.js?v={vb:raw vboptions.simpleversion}';
var fcb_var = document.getElementsByTagName('script')[0];  
fcb_var.parentNode.insertBefore(fcb_js, fcb_var);
</script>

or

<script type="text/javascript">
(function() {
var test = document.createElement('script'); 
test.type = 'text/javascript'; 
test.async = true;
test.src ='/clientscript/vbulletin_facebook.js?v={vb:raw vboptions.simpleversion}';
var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(test, s); })();
</script>

Now my problem is that, vbulletin_facebook.js is loading correctly but, I can't connect with facebook as guest or as a member... Now I assume that has an if statement of facebook java, later than the actual statement of vbulletin variable.. Again this seems wrong, because I didn't change any range of any variables instead of actual java architecture, if I try to load the .js normally is working correct...

Any ideas??

Note:: any kind of page tester that I test my forum seems to detect the vbulletin_facebook.js at the same position as with the standard code... md5.js and vbulletin-markert.js
are loaded and seems to work fine, and css files such as additional.css etc are not tested yet but I think may have a problem with that too!!!

Thank you !!

*SOLVED*

It's working as below:

<script type="text/javascript">
(function() {
var s = document.createElement('SCRIPT'), s1 = document.getElementsByTagName('SCRIPT')[0];
s.type = 'text/javascript';
s.async = true;
s.src = '/clientscript/vbulletin-core.js?v={vb:raw vboptions.simpleversion}';
s1.parentNode.insertBefore(s, s1);
})(); 
</script>

facebook java doesn't work with the following function, probably because the js of facebook it's call via vb raw before the main code so function is loaded normall but connectivity avoided.!!

If you want to use the defer js, for all your java files used above code. if your using cdn it will not work, so you need to replace the source with the exactly address, for example::

'http://pullzone-anymvs.netdna-cdn.com/clientscript/vbulletin-core.js?v={vb:raw vboptions.simpleversion}'

at the end if you have cache control you must remove the query from the actual js file, so need to remove
?v={vb:raw vboptions.simpleversion} from all your js file after you enable cache header..

Note: This is working for me and it's a good idea to used it especially if your running on a simple hosting. it will not make your side load 10 times faster but it will reduce the time load of js files at all, especially for users that they use IE as browsing.

TIP: load your css files as

<link rel="stylesheet" type="text/css" href="http://pullzone-anymvs.netdna-cdn.com/clientscript/vbulletin_css/style00014l/additional.css" />

don't used vb raw variables, are very lag and have no sense!!
